TO ALL WHOM IT MAY CONCERN:

Be it known that I,' WILLIAM H. WILLSON, of the'city, county, and Stateof New York, have invented certain new and useful Improvements inHand-Brushing aud Polishing-Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had, to the accompanying drawings, making a portion of thisspecication', i n which- Figure 1 is a longitudinal section `of anapparatus made according to my invention.

Figure 2 is a transverse section of the same, taken in the line :e :e ofiig. 1.

Figure 3 is a transversesection of the same, taken in the line y y ofiig. 1.

Figure 4 is a transverse section of the same, taken in the line z z ofgrl.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention consists in-a coiled spring and a systen of gearingarranged within the cylindrical body of a rotary brushing andpolishing-device, furnished with suitable axial handles, in such manneras to produce the requisite rotatory movement ofthe same, the objectbeing to provide a rotary apparatus for the purposes indicated, whichmay be operated by hand, thereby dispensing with power as ordinarilyapplied to this class of devices.

The invention further consists in so arranging a friction-brake withinthe cylindrical body just named that the rotatory movement olf/'thelatter may be readily stoppedwhen desired.

The invention further consists ina novel combination of.parts,vwherebythe eicient operation of the apparatus, and the convenience with whichit may h'e handled or manipulated, is materially increased.

To enable others to understand-the construction and operation of myinvention, I will proceed to describe it with reference to thed-rawingsil A represents avfraxne, composed of two circular disks, a,`and an end bar, e, these parts being connected by suitable braces, a',working inA bearings provided in the disk b and bar c. V

In the axial line ofthe'cylindrical body B, hereinafterdescribed, is astem, C, this stem being provided, at its outer end, with a handle,vA*.i v

Between the bar c und disk b is a coiled spring, D, shownin fig. 1, andalso indicated in red outline in iig. le The inner end of this spring isattached to the stem C, and the outer extremity thereof is connectedwith' one of the braces a, ofthe frame A, in such a way that theuncoiling of the spring will rotate the stem Cjust mentioned lwithreference to such frame. t v

The stem C has attached thereto a ratchet-wheel, d, and placed looselythereon is a spur-gear, e, furnished at one side with a spring-pawl, b',working with or into the ratchet-wheel Z in such manner thatw during theuncoiling of the spring the spur-gear e will be turned with the stem C,but in the ceiling of the spring the pawl will slip over theratchet-wheel, thereby enabling the apparatus to be wound up for use.

The spur-gear gears into n pinion,f, upon a shaft, e', which extendsfrom on`e of the disks a 6to the other,

and is provided with a spur-wheel, g, which,n acting through a pinion,z, spur-wheel z", and pinion j, rotates a shaft, e', upon the extremityof which, at the inner side of the disk 6, is a friction-pinion, m,which is placed in contact 'with the inner edge of an internalcylindrical shell, E, which is secured upon an axial shaft, E',furnished at its outer end with a handle, B*, and having its 'innerendscrewed firmly into `the centre of thedsk of the frame A. 4 I

Secured externally upon the lshell E is the cylindrical body B of theapparatus, the shell just mentioned being formed, in the first instance,separately from the body, merely for the sake of convenience iuconstruction, and constituting, in fact, a portion of the`body itself. YI

The exterior of the body B, when the apparatus is to be' used forbrushing purposes, is provided with radial bristles, :1s represented inred outline in igs. 1 and 4, 'out when designed for polishingv purposes,the surface of such body is coated with emery, or equivalentubrading-materinl. I i

lhe springs 1 ),'having been coiled by turning the handle A* of tbe stemC in the requisite direction, operates,l when unwinding or uncoiling,through the stem C and the system of gears hereinbef'ore described, torotatethe friction-pinionm, which, in its turn, communicates a rotatorymovement to the body B, the body being held or sustained bythe handle B*in suitable contact or proximity-with the article to be brushed orpolished, as the oase may he, the other handle, Al, that ofthe stem C,being left loose orvonly slightly supported by the hand of the personusing the apparatus, so that it may be free to turn in the operation ofthe latter, as just hereinbefore described. v e

In order'that the apparatus may, when required, be retained vvith itsspring in a coiled or wound-up condition, and that its movement may bestopped with facility when desired, a brake, consisting of ase'micircular spring, I, is secured, at its middle, to a plate, 0*,fixed upon the shaft F, at the inner end of the handle B* thereof, theend portions of such brake,.when the latter is expanded, beingpressedagainst the interior of the shell E, or, in other words, ofv the body B,with s'uicie'ntforce to neutralize that exerted by the coiled spring D,which operates to rotate such body, ,thereby stopping the movement ofthe latter.

Extending from one end portion ofthe spring or brake I to the other, isa chain or strap, 1', the centre of which is attached to the inner endofa lever, 11 passing through the plate 0*, with its opposite endsituated in such relation with the handle B* that it may be convenientlypressed toward the 'same to draw upon the chain or strap just mentioned,so as to bring the end portions of the brake inward away from theinternal surface of the shell E, thereby permitting the rotation, ashereinbefor'e set forth, of the body B, of which such shell forms apart, it being only necessary to release the lever 'in order to permitthe brake to operate to stop the motion of the body B, as justmentioned.

What I claim as my invention, and desire to secure by Letters Patent,isf

1. So arranging the coiled spring and the system of gearing within thecylindrical body furnished with axial handles, as to secure the rotatorymovement of such body, substantially as herein set forth.

2. The arrangement of the friction-brake within the cylindrical bodyfurnished with axial handles, whereby the rotatory movement of the samemay be stopped, substantially as herein set forth.

3. The arrangement of the coiled spring, the system of gearing, the stemofthe handle A*, and the frame A, with reference to eachother and thefriction-pinion m, dividing the cylindrical body B, substantially as andfor the purpose specified.
